5 things every computer user needs to know how to do

Feb 9 2013 12:01 am

A good number of computer users think the answer to their tech problems is to ignore the symptoms, upgrade to fancier software or buy a new computer.

Here are five things that won’t turn you into a tech guru overnight, but they’ll keep your computer running fast, make you more productive and save you tons of frustration. Best of all, they won’t cost you a cent.

If you’re the tech support person for your family and friends, share this with them.

1. Work faster using keyboard shortcuts: The great thing about computers is that they can work much faster than you can. But telling them what to do is often a slow process. Well, there’s a fix for that. Say you’re ready to print a document. Instead of using the mouse to move a cursor around the screen and selecting “Print” from a drop-down menu, just hit Control+p on your keyboard.

There are dozens of keyboard shortcuts like this, from pressing Ctrl+s to save the file you’re working on, to pressing Ctrl+z to undo a boo-boo.

It takes a little getting used to at first, but after you try keyboard shortcuts for a while, I guarantee that your mouse will start gathering dust.

Click here to learn my 5 essential keyboard shortcuts: www.komando.com/tips/index.aspx?id=13933. I also sell several comprehensive shortcut guides in my store. These cover all the time-saving shortcuts for Windows, OS X, Google services, the major Web browsers and iTunes.

Every computer you own should have an antivirus program, a firewall and an antispyware program. If you’re missing one or more of these, head over to my Security Center at www.komando.com/securitycenter to download free security programs.

Another huge threat right now is security holes in Java, a programming language used by Web browsers to run interactive content.

When a vulnerable version of Java is active in a Web browser, visiting a compromised website is all it takes for crooks to sneak malware onto your computer. In most cases, you won’t even know the site is compromised until it’s too late. To stay safe, stop using Java, or stay on top of the upgrades and use Java a lot more guardedly.

3. Share large files the easy way: The Internet was designed to make sharing information easy. But we’ve all run into roadblocks trying to share larger files by email. Sending large files through email is slow, can hit attachment size limits or fill up recipient inboxes. Fortunately, there are easier ways to share large files. These three popular sites will get the job done for you: Dropbox, WikiSend and Senduit.

4. Fix Wi-Fi problems: Nothing’s worse than a spotty and sluggish wireless network. Movies stop to buffer, online games lag and video calls drop. First, double-check that the Internet speed you’re getting is as fast as what you are paying for. This service will give your Internet connection a quick speed test: www.komando.com/downloads/category.aspx?id=3917.

Make sure your wireless network is encrypted. A sudden drop-off in wireless network speed could be a sign that your neighbors are using your open connection to surf and download files. Click here for detailed instructions on encrypting your network: www.komando.com/tips/index.aspx?id=11766.

If parts of your home are Wi-Fi dead spots or get weak signals, try placing the router in an open, central location away from walls and obstructions, such as metal filing cabinets.

You also could try the trusty beer-can hack. This involves cutting a beer or soda can open with a utility knife to make a parabolic antenna out of it. This offbeat trick can boost your network by two bars or more. It’s easy, and I made a fun video to show you exactly how to do it. Watch it now: http://bit.ly/oqdFQC.

5. Perform regular maintenance and make backups: Keep your software up to date. Updates fix bugs and improve the stability of your operating system and programs.

If you spend more than two minutes a day looking for files on your hard drive, it’s time to organize files and clear out old stuff. These freebies will help you: www.komando.com/downloads/category.aspx?id=10397. Keeping a block of free space on your hard drive also will boost to your operating system.

Of course, the most important maintenance tip I can give is to back up your data with a cloud-based solution. There are many services available. The service I recommend is Carbonite. It is an advertiser of my national radio, but I’ve used its services for years even before they were an advertiser.
